Steps to Adjust Clutch
For the clutch pedal of Scion FRS, it is usually considered to be relatively lighter than other cars’ clutch pedals. If the lack of feel annoys you, then there are some simple steps that you can follow to adjust the clutch pedal as per your liking. Without the help of any mechanic, you can adjust the pedal to shorten the travel distance and enhance it’s responsiveness. Follow the steps mentioned below.
- The first thing you need to do is to find the master cylinder. You’ll find it above the accelerator pedal, but you can also use the clutch pedal to locate it. To use the clutch pedal to find the master cylinder, press the pedal and see what moves.
- The next thing you need to do is to locate the nut behind the bracket. You need to loosen this nut so use a 12mm open-ended wrench to rotate it clockwise to open it. If you feel it getting tighter, change the direction. The purpose is to loosen or open the nut.
- After loosening the nut, press the clutch pedal and then rotate the shaft that is going to the master cylinder located before. You need to rotate the shaft anti-clockwise. You can use pliers or grippy gloves to rotate it smoothly and slowly.
- While you rotate the shaft, keep a check on the height of the pedal. If you find pedal at the same level as the brake, you need to stop immediately. It is preferred to keep the clutch pedal slightly below the brake pedal.
Adjusting the Cruise Control Sensor
After adjusting the clutch pedal, you also need to adjust the switch that detects the highest point of the clutch pedal. How do you adjust this sensor? Following the simple steps mentioned below.
- This sensor is held at its place using 2 nuts, one on each side. Loosen one of these nuts by rotating it using a wrench. Consider this loosened nut to be nut A and the one untouched nut to be nut B.
- After loosening the nut A, hold the sensor and then turn the nut B clockwise. Since you won’t be able to reach this nut using wrench, use your fingers. While you’re doing this, press the sensor towards the white pad on the clutch pedal arm in a periodic motion.
- Keep rotating the nut B while periodically pushing the sensor towards white pad of clutch pedal arm. Once you feel the sensor’s threaded portion to be touching the white pad of clutch pedal arm, stop rotating the nut B. It should not be touching the white pad.
- After this, tighten the initially loosened nut A.
- This marks the completion of clutch adjustment, but there are some tests that need to be performed to make sure it’s safe to drive around the car now.
- Drive in the car and shift in all gears, including reverse. If you hear any resistance or grinding when shifting gear then you need to readjust the height of clutch pedal by increasing the pedal height.
- In order to readjust, you will be following all the steps mentioned above for the adjustment of the gear. Remember to adjust the sensor first to give enough room to the pedal for adjustment.
- After readjustment, run the tests again and if you experience smooth shifting of gears, the car is safe to be driven around now with faster and easier gear shifting.
